I use i386 6.0 Stable and amd64 6.0 Stable.

Defaults are there. I looked at them, the GENERIC config, NOTES and 
whatever else I could find to look at. No touching them, just 'cp 
GENERIC CUSTOMconf. I did find that there were some things that I used 
to be able to comment out in 4.x and 5.x CUSTOMconf's that I won't 
build with my 6.x CUSTOMconf.

They are in i386, but npx isn't in amd64 defaults. 

John, go back to the OP and help him, I'M not having a problem at this 
time. I was just making suggestions and comments in hopes of helping 
someone else. That's why I suggested you might want to email me 
privately rather than post to the list. Pretty soon my knowledge is 
going to show up and be seen by everyone as being somewhat not up to 
speed.
